System and method for modulating audio effects of speakers in a sound system

Abstract

A system for modulating audio effects of speakers is provided. The system includes a selecting module, a playing module, a recording module, a time delay computing module and a modulating module. Based on these modules, the system is capable of determining a time difference and a pitch for each of the speakers, and modulating the time difference and the pitch for each of the speakers to a desired time difference and a desired pitch, so as to ensure that simultaneous sounds from each speaker arrive at a microphone at about the same time and with the same audio pitch. A related method is also provided.

Description

BACKGROUND[0001]1. Field of the Invention[0002]Embodiments of the present disclosure relate to audio signal analyzing systems and methods, and particularly to a system and method for modulating audio effects of speakers in a sound system.[0003]2. Description of Related Art[0004]In any sound system, ultimate sound quality depends on how the quality of the speakers in the sound system. A speaker is a component that takes an audio signal stored on storage like compact disks (CDs), tapes and digital video disks (DVDs), and turns the audio signal back into sound waves that people can hear. Generally, a sound system has more than one speaker, and sound systems that provide better surround-sound effect generally has more that one speaker. For example, the type of 2.1 channel surround sound system has a left channel speaker, a right channel speaker and a super-undertone speaker, and the type of 5.1 channel surround sound system has a front-left channel speaker, a front-right channel speaker...

AI Technical Summary

Benefits of technology

[0007]A system for modulating audio effects of speakers is provided. The system comprises a selecting module, a playing module, a recording module, a time difference computing module and a modulating module. The selecting module is configured for selecting a speaker from the speakers, and powering the selected speaker on. The playing module is configured for playing an original audio file stored in a storage device to generate an audio signal, and further configured for outputting the audio signal via the selected speaker. The recording module is configured for recording the audio signal as a new audio file via a microphone, and further configured for recording a playing start time and a recording start time. The time difference computing module is configured for computing a time difference between the playing start time and the recording start time. The pitch obtaining module is configured for obtaining a pitch from the new audio file. The modulating module is configured for modulating the time difference and the pitch to a desired time difference and a desired pitch for each of the speakers.

Problems solved by technology

However, it's difficult to ensure that speakers in the surround sound system have the above characteristics once they are produced.
